Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a Brown's frame which is convenient for adjusting traction force. Background Art

[0002] The Brown frame is also called the Brown frame or Brown frame. It is mainly used for traction reduction of lower limb fractures. It is suitable for orthopedics, surgery and rehabilitation physiotherapy. When in use, the traction frame is placed at the end of the bed with the pulley end facing outward, and then the support piece at the needle insertion site of the affected limb is adjusted to make the pulley height position in an appropriate position, and the traction bow is introduced into the pulley groove. One end is connected to the traction bow that fixes the traction needle, and a weight or hammer is hung on the other end for traction. The traction force is controlled according to the reduction situation.

[0003] With respect to the above-mentioned related technologies, the inventors found that the degree of recovery of patients' legs and the shapes of their legs are different, which leads to different tolerance ranges of traction forces. The traction suspension gravity is generally pulled down by weights or hammers. When placing weights or hammers, it is impossible to accurately apply the traction force that the patient can withstand, and the weights or hammers need to be replaced continuously. During this process, if the traction force exceeds the patient's tolerance range, it will cause discomfort in the patient's legs, and there is a certain degree of cumbersomeness in adjusting the traction force by replacing weights or hammers. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a Brown's frame which is convenient for adjusting the traction force, so as to accurately adjust the traction force to the range required by the patient and reduce the complexity of adjusting the traction force.

[0019] In a preferred example, the utility model can be further configured as follows: a counterweight water tank is placed on the top of the base frame, and limiting grooves are provided on both sides of the bottom of the counterweight water tank, and the limiting grooves are matched with both sides of the base frame.

As the liquid is continuously injected, the traction force at this time can be observed through the dynamometer, so that the traction force can be controlled within the patient's optimal tolerance range and the accuracy of the traction force can be improved. The excess liquid can also be discharged along the water outlet hose through the roller clamp to reduce the cumbersomeness of adjusting the traction force.

The bottom of the counterweight water box 741 is conical and connected to the top of the water outlet hose 744, which is convenient for drainage and can prevent the generation of liquid accumulation in the counterweight water box 741. In addition, the counterweight water box 741 is preferably made of PP material or acrylic material. When no water is filled, the mass of the counterweight water box 741 itself is reduced, and the water outlet hose 744 is used to control the drainage through the roller clamp 745. When draining water, a water receiving bucket is placed at the drainage end of the water outlet hose 744 to collect water for recycling. When filling with water and counterweighting, the liquid is injected into the counterweight water box 741 along the water injection port 743.

The adjustment rod 13 includes a vertical rod 131 and a sleeve rod 132 sleeved on the surface. A plurality of adjustment holes 133 are spaced apart on the vertical rod 131. An adjustment bolt 134 is passed through the bottom end of the sleeve rod 132, and the adjustment bolt 134 is threadedly connected with the corresponding adjustment hole 133; the support pad 14 is made of nylon. Due to the difference in body shape of patients, their leg lengths are also different. Therefore, during the physical therapy process, the height of the joint during traction is also different. At this time, the sleeve rod 132 can be adjusted up and down on the surface of the vertical rod 131 by rotating the adjustment bolt 134 and adjusted to a suitable height. Then the adjustment bolt 134 is installed with the corresponding adjustment hole 133 to adapt to the patient's leg.

[0042] The adjusting mechanism 60 includes a rotating rod 61, which is rotatably connected between the adjusting rods 13. A limit block 62 is installed on the rotating rod 61, and a driving rod 63 is inserted on the limit block 62. Two butterfly nuts 64 are symmetrically threaded on the driving rod 63. The butterfly nuts 64 are respectively distributed on both sides of the limit block 62 and are connected to it in a conflicting manner. One end of the driving rod 63 away from the limit block 62 is hinged with a hinge seat 65 through a pin shaft. The adjusting frame assembly 20 includes an arc-shaped bracket 21, an arc rod 1 22 is connected between the inner sides of the arc-shaped bracket 21, and the bottom of the arc rod 1 22 is connected to the hinge seat 65.

The patient's leg length is different, and the yield degree of their thigh and calf when bent is different. In order to ensure the comfort of the patient's leg during traction, the two butterfly nuts 64 can be rotated to form a corresponding yielding space between the two, and then the driving rod 63 is pushed or retracted to make the adjustment frame assembly 20 or the leg bracket assembly 30 swing, and its slope inclination angle is adjusted to adapt to the support angle of the leg and the traction angle when the pulley 5 is pulled, and then the two butterfly nuts 64 are driven to move toward each other to clamp and fix the limit block 62 to ensure that the adjustment frame assembly 20 or the leg bracket assembly 30 is supported and stable.

[0043] A counterweight water tank 8 is placed on the top of the base frame 11, and limiting grooves 9 are provided on both sides of the bottom of the counterweight water tank 8, and the limiting grooves 9 fit with both sides of the base frame 11; when the patient's thigh and calf are bent, the force on his leg is located on one side of the leg bracket assembly 30. To prevent the other end of the support frame assembly 10 from tilting, the limiting grooves 9 are clamped with both sides of the base frame 11, so that the weight of the counterweight water tank 8 is applied to the base frame 11 to ensure the overall stability of the support frame assembly 10.

[0044] The implementation principle of this embodiment is: when in use, the patient's legs are wrapped and tied with a strap 71, and then the calf and leg are slowly moved to the support frame assembly 10 and located on the support pad 14, and the thigh is located at the leg support assembly 30, and one end of the traction rope 72 is tied with the strap 71 or connected by a hook, and then the traction rope 72 is introduced into the pulley groove of the pulley 5 in sequence, and the traction end of the traction rope 72 is hung with a dynamometer 73, and a counterweight water box 741 is hung under the dynamometer 73, and then water filling and counterweighting are started, and the liquid is injected into the counterweight water box 741 along the water injection port 743. As the liquid is continuously injected, the traction force at this time can be determined by observing the pointer reading of the dynamometer 73, and the traction force can be controlled within the patient's optimal tolerance range. This method is not only accurate, but also saves the tediousness of hanging weights or heavy hammers on a conventional Brown's frame for traction.

[0045] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
